Bespoke programme for Wordpress based site

I am looking for someone to develop a bespoke programme/plugin for a Wordpress based website. The programme must work on multiple platforms and devices.
The function of the plugin is for users of my site to log and record statistics of their football players. Users will record training sessions and games through the plugin. The programme will feed back through pie charts, graphs and tables statistics based on the information the user provides.
The plugin wil also allow for the PDF export.
